Hitachi Energy has won an order from TenneT and TransnetBW , two of Germany’s four transmission system operators, to supply a transmission solution for the SuedLink DC4 HVDC interconnection between the north and south of the country.
Using Hitachi Energy’s HVDC Light technology, SuedLink DC4 will transfer up to 2000 MW of emission-free electricity. The link will transmit at ±525 kV for 550 km underground, transmitting either power from wind farms in the north to the south or from solar plants in the south to the north as required by the demand/supply balance.
Hitachi Energy will supply an HVDC Light converter station at each end of SuedLink DC4 to convert AC power from the transmitting grid to DC for transmission through the link, and back to AC at the receiving grid. The contract includes three cable section stations to speed up fault detection in the link.
SuedLink DC4 is one of the most important power grid and energy transition projects in Germany. It will help Germany’s energy transition, enabling a reduction in the use of fossil fuels and help the country achieve carbon neutrality by 2045.
Niklas Persson, Managing Director of Hitachi Energy’s Grid Integration business, said: “We are proud to play a crucial role in this very important investment in Germany’s transition to renewable energy and carbon neutrality. HVDC Light is the enabling technology for large-scale transfers of energy, both onshore and offshore.”
